DlSTENTlON-VALVE FOR MUSICAL INSTRUMENTS.

SPECIFICATION formingpart of Letters Patent No. 572,799, dated December8, 1896.

Application filed March 25, 1896. Serial No. 584,863. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM FLINT HENRY, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented a new and 1111- provedDistention-Valve for Musical Instruments, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improveddistention-valve for cornets and like musical instruments which issimple and durable in construction and arranged to prevent sidewisemotion of the valve by the buckling of the compressionspring now used incornets.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is asimilar view of the same with the valve in an inward or pressedposition, and Fig. 3 is a face view of the spring and valve.

The tubular casing A of a cornet contains the usual valve 13, providedwith a stem 0, fitted to slide at its outer end in a cap D, secured tothe outer end of the casing A. On the outer end of the stem C is secureda fingerpiece E, adapted to be pressed by the player to move the valve Bin the casing A and graduate the tone as desired.

On the inner end of the stem 0 next to the valve 13 is arranged a diskF, in which is secured one end of a spring G, coiled on the stem C andpreferably made conical, with the outer or base end G resting on ashoulder A, formed integral on the outer end of the casing A next to thecap D. Now it will be seen that by the arrangement described the tensionof the spring G tends to hold the valve B in an outermost position, theoutward movement of the valve being limited by a collar H, secured onthe stem 0 and adapted to rest on the inner face of the cap D. Then thefinger-piece E is pressed inwardly to operate the valve 13, then thespring G is extended, and as soon as the operator releases the pressureon the finger-piece the tension of the spring G pulls the valve 13 backto its normal position. Now it will be seen that by using the springthat is extended on pressing the finger-piece E, I prevent buckling ofthe spring and consequent sidewise pushing of the valve B in the casingA, and in doing so the valve will always be in a central position,thereby rendering the action equal and sure and never permitting thevalve to stick on one side or the other of the casing, as is sofrequently the case in valves for cornets as ordinarily constructed. Itwill further be seen that as the valve B always moves centrally in thecasing the wear on the casing and valve surfaces is reduced to aminimum.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A valve for musical instruments, comprisinga casing, a valve fitted to slide therein and provided with avalve-stem, and a spring having its lower end connected with the valveand resting with its other end on an outwardly-facing shoulder orbearing on the easing, substantially as shown and described.

A valve for musical instruments, comprising a casing provided at itsouter end with an enlarged bore forming an upwardlyfacing shoulder, avalve fitted to slide in said casing and provided with a stem extendingto the outside thereof, a coiled spring tapering toward one end andhaving its larger end in engagement with said shoulder while the innerend of the spring is secured to the valve, substantially as described.

3. In a musical instrument, substantially as described, the combinationof the barrel or valve-casing, the valve fitted therein and having thestem, and the coil-spring encircling the valve-stem, said spring beingconnected at its lower end with the valve and having at its upper end anapproximatelycircular bearing concentric with the valve whereby as thevalve is depressed the spring will be distended and the spring beingarranged concentric with the valve whereby to overcome the crowding overof the valve against one side of the casing, substantially as shown anddescribed.
